UV lamp illuminating security banknote with invisible inks and blockchain hash network for anti-counterfeit protection.
Anti-counterfeit printing combines covert inks that respond to ultraviolet (UV) or infrared (IR) light with serialized codes recorded on a blockchain ledger. The ink binds authentication to the physical item, while the ledger stores one 256-bit cryptographic hash per serial that exposes altered records. The ledger alone cannot confirm that […]

Modern 3D representation of a Key Line Drawing (KLD) showing precise cut lines, crease lines, and glue flap boundaries overlaid on a folding carton.
A key line drawing in packaging (KLD in Packaging) is a flat, 1:1 scale technical drawing of a packaging structure showing cut lines, crease lines, perforations, and glue flaps. Most converters treat KLD and dieline as synonyms. Die-makers build the cutting die from the KLD geometry, and prepress places artwork, […]
